An integrated valve assembly including a valve body defining at least two separate valves is disclosed. The valve assembly can be used, for example in an interface between an aseptic or pasteurized product supply vessel, one or more product dispensing machines, and a cleaning liquid supply vessel. The valve body can optionally be made in one piece, as by casting and machining a block of suitable metal such as stainless steel. Optionally, all of the interior surfaces of the valve body can be non-pooling surfaces which self-drain through at least one of the first, second, and third ports when the valve body is in the normal orientation and the necessary valves are open. The second face of the second weir optionally can be merged with the surfaces defining the second passage. Dead-legs and discontinuities in the valves which can collect undesired deposits are minimized, the size and weight of the valve assemblies are reduced, and the respective orientations of the integrated valves are fixed so the valves will operate and drain properly. |
